When auto-hide is on, Show Again Tab missing?

Hi, this works on my site and also on the default WP themes (2010 and up). If it’s not working on yours then you could try a few of the suggestions on http://www.cookielawinfo.com/troubleshooting. Cookie Bar display errors are usually caused by incorrect use of wp_head(), wp_footer() or wp_enqueue_scripts() – usually hardcoding jQuery – and also by clashes with JavaScripts in other plugins or within your theme. If you’re technically minded then you can use e.g. Firebug to find the cause. Hope that helps.
